摘要
针对传统水下地形测量存在外业工作强度大、作业效率低、作业船吃水较深、人员有涉水危险等困难情况,创新采用新型无人船测量系统解决水下测量难题,并介绍了无人船测量系统的基本组成和功能及水下测量系统的测量原理。实践表明利用无人船测量系统对库区水下地形进行测量,能快速获取水下地形数据,提高水下地形测绘效率的同时又避免了人员涉水危险,为水下地形测量提供了一种新的解决方案。
There are many difficulties in the traditional underwater topographic survey than on the ground,such as intensive work,low efficiency,shallow draft and the danger of wading,usinganew type of unmanned surface vehicle surveying system to solve these difficulties,meanwhile introduces the composition and function of the system,and the principle of water-depth measurement and underwater topographic survey. Avoids the risk of personnel wading,improvesthe efficiency of underwater topographic surveying and got the underwater topographic data more efficientby using the unmanned surface vehicle. Through the application,it is found that this technology is a new solution for underwater topographic survey.
